The behavior of cerium(III) on the Mo electrode in eutectic LiCl-KCl melt was investigated by using electrochemical transient techniques at 673 to 783K. The results indicated that the reduction process of cerium(III) to cerium metal was a single exchange step of 3 electrons which was controlled by the diffusion of cerium(III). The diffusion coefficients (DCe(III)) were determined by using cyclic voltammetry, chronopotentiometry and square-wave voltammetry, and could be described by: ln[D] = -2.129 - 5704/T.
